Abstract

本实用新型涉及一种拱形结构桥梁，包括砼桩、桥墩和路面层构成，在砼桩与桥墩之间铺设基层，两桥墩之间架设拱形砼梁，拱形砼梁与路面层之间设填充料层。拱形砼梁可为一个或多个。该基层及填充料层均由废矿渣或粉煤灰与水泥混合制成。本实用新型有效利用了废矿渣和粉煤灰，使废弃物得到综合利用，变废为宝。同时，减少了矿渣、粉煤灰的大量堆积储存对空气、水源环境的污染，同时减少工程取土大量占用耕地。本实用新型的拱形桥梁尤其在修建山区公路中能发挥重要作用。可保护环境，并提高公路的综合效益。

Description

拱形结构桥梁
技术领域
本实用新型涉及桥梁，特别涉及一种拱形结构桥梁，属于国际专利分类E01D4/00“拱桥”技术领域。
背景技术
目前，在山区修建公路，需要开凿很多隧道，铺架高架桥。大量填挖山体会造成山体滑坡，破坏山区涵养水分，引起不良的地质灾害。工程取土又大量占用耕地，并且公路的造价非常昂贵。另一方面，山区工业生产的副产物废矿渣和粉煤灰大量堆积储存，对空气和水源环境造成污染。
发明内容
本实用新型的目的，在于合理有效地利用废弃物，变废为宝，提供一种桥梁承重力大，坚固耐用的拱形结构桥梁。
本实用新型的目的是通过以下技术方案实现的。
拱形结构桥梁，包括砼桩、桥墩和路面层构成，在砼桩和桥墩之间铺设有基层，在两桥墩之间架设拱形砼梁，在拱形砼梁与路面层之间设有填充料层。所述的拱形砼梁可设有一个或多个。所述的基层、填充料层均是由废矿渣或粉煤灰与水泥材料混合制成的。
本实用新型有效利用了废矿渣和粉煤灰，使废弃物得到综合利用，变废为宝。同时，减少了矿渣、粉煤灰的大量堆积储存对空气、水源环境的污染，同时减少工程取土大量占用耕地。本实用新型的拱形桥梁尤其在修建山区公路中能发挥重要作用。可保护环境，并提高公路的综合效益。
附图说明
附图为本实用新型拱形结构桥梁的结构示意图。
图中：1、路面层，2、填充料层，3、桥墩，4、基层，5、砼桩，6、拱形砼梁，7、拱形孔。
具体实施方式
如附图所示，一种拱形结构桥梁，由路面层1，矿渣(或粉煤灰)与水泥的混合填充料层2，桥墩3，基层4，地下砼桩5，及两桥墩间的拱形砼梁6构成。其建筑结构是：先在地下打上数根砼桩5，然后用废矿渣(或粉煤灰)与水泥混和料铺设基层4，拱形桥桥墩3座在基层4上，在两桥墩3之间修建拱形砼梁6，最上层铺设路面层1。路面层1与拱形砼梁6间用矿渣(或粉煤灰)与水泥混合物填充，形成填充料层2。
该桥的整体结构由一个或多个拱形结构构成，当桥面受到重压时，根据力的传递原理，拱形结构能把压力分散到各个桥墩上，因此拱形桥比其它桥梁承重力大，坚固耐用。
该拱形结构桥，有效利用废矿渣和粉煤灰，减少了矿渣、粉煤灰大量堆积储存对空气、水源环境的污染，使废弃物得到综合利用，变废为宝；同时减少工程取土大量占用耕地。
本实用新型的拱形桥梁，尤其在修建山区公路中能发挥重要作用。山区公路的修建需要开凿很多隧道、铺架高架桥，大量填挖山体会造成山体滑坡，破坏山区涵养水分等，引起不良地质灾害，并且公路的造价非常昂贵。
采用本实用新型的拱形桥设计，使修建山区公路布线灵活，充分顺应了地形、地貌特点，使路线符合自然，依赖自然，减少隧道开凿。同时有效利用了矿渣、粉煤灰等废弃物，是同跨度高架桥造价的1/5。有利于保护环境，提高公路的综合效益。
